Endometriosis was detected in 42 cases out of 566 patients undergoing laparoscopic tubal sterilization. The presence of endometriosis was then correlated with previous contraception. Those patients using no contraception, or barrier contraception alone, were regarded as controls. Previous oral contraceptive use was associated with a lower incidence of endometriosis, although the difference was not significant. A significantly higher incidence (P less than .05) of endometriosis was present in former intrauterine device users, possibly because of retrograde flow of increased menses.
在566例接受腹腔镜输卵管绝育术的患者中，有42例被检测出患有子宫内膜异位症。然后将子宫内膜异位症的存在与先前的避孕方法进行关联分析。那些未采取任何避孕措施或仅采用屏障避孕法的患者被视为对照组。既往使用口服避孕药与子宫内膜异位症的较低发病率相关，尽管差异并不显著。既往使用宫内节育器的患者中，子宫内膜异位症的发病率显著更高（P小于0.05），这可能是由于经量增加导致的逆行性月经所致。
